Title: Data printer
IPC: G06K15/10
Filed: 1974-07-10
Abstract: 1468242 Control of printers EXTEL CORP 10 July 1974 [12 Sept 1973] 30660/74 Heading G4H A printer incorporates means 101 for automatically effecting a temporary reversible line feed operation between printing operations in order that the data just printed may be read without obstruction by components of the printer. As described, a dot-matrix printer 51 &c. receives data from a line 72 or a keyboard 43 which is fed to a store 76. The apparatus detects when the final stage of store 76 is empty (signal 102) and effects the temporary line feed; when new data reaches the penultimate stage of store 76 (signal 103), the line feed is reversed and printing is resumed. Thus the terminal portion of the text is always fully visible whenever the printer is not actually proceeding with a printing operation. The obstructing component may be an ink ribbon, or the print head itself.

Abstract: 355,097. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Franklin, C. S. ; 1736, Van Ness Avenue, Hollywood, California, U.S.A.) Oct. 15, 1930, No. 30901. Convention date, Oct. 16, 1929. [Class 40 (i).] In a method of indicating at a distance the readings of an integrating meter provided with a number of dials and co-operating pointers for the purpose of indicating a quantity having a number of digits, the pointers are associated with frequencyvarying means which are successively connected to a source of electric oscillations to vary the frequency thereof. The currents of variable frequency may be transmitted over wires to the distant station or they may be caused to modulate a high-frequency current, as described in Specification 291,092, [Class 40 (i), Electric signalling systems &c.]. In the construction shown, an integrating meter M is provided with dials 2 .. 5 and co-operating pointers carried by shafts actuated by the meter mechanism. Each shaft is provided with a cam C adapted to engage one end of a pivoted lever L, the other end being attached to the movable plate of a variable condenser indicated by 2<111>, 3<111>, 4<111> or 5<111>. The transmitter 1 is of the type set forth in Specification 291,092 and the modulating current of the transmitter is preferably supplied from an alternating current source comprising two oscillators of different frequency, the output currents of which produce a beat frequency supplied to the modulating circuit of the transmitter. The oscillatory circuit O of one of those oscillation generators is connected successively to the variable condensers 2<111> .. 5<111>. A meter 6 of ordinary voltmeter or ammeter type in which the index moves.through a comparatively small arc of a circle, is also shown, which controls the capacity of a variable condenser 6<111> adapted also to be connected to the oscillatory circuit O. The distributers 7, 71, 20 and 18, 21 are driven stepby-step by periodic interruptions of the carrier current, and are synchronized at the end of each cycle by a long interruption. The period of association of each pointer or of the meter 6 with the line, and the period of the long interruption at the end of each cycle, are determined by the time of discharge of a condenser 31 in the grid circuit of a valve 29, and the period of the short interruptions is determined by a slow-release relay 26. The operation of the distributers is identical with that described in Specification 293,037, [Class 40 (i), Electric signalling systems &c.].

Title: Improvements in and relating to frequency modulation detectors
IPC: H03D3/12
Filed: 1948-11-29
Abstract: 648,129. Frequency modulation. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 29, 1948, No. 30918. Convention date, Nov. 29, 1947. [Class 40 (v)] In order to reduce the response of a F.M. receiver when off-tune, the rectifiers 9, 10 of a phasing or other discriminator of normal type are provided with control grids 20, 21, each of which is connected to its own cathode by an audio byepass condenser 23, 25, and to the opposite cathode by a resistor 22, 24. When the receiver is slightly mis-tuned, there is a D.C. voltage between the two cathodes, which is transferred to the opposite grids, in such sense as to reduce the current flowing through the more active rectifier. In this way, the off-tune output of the receiver is reduced below its normal in-tune output, and correct tuning may be obtained by listening for maximum output.

Filed: 1927-11-18
Abstract: 306,574. Whiffin, W. W. Nov. 18, 1927. Dashpots, applications of.- A retarding device for switches, gas cocks, &c. causing them to be automatically switched off, e.g. a certain time after they have been switched on by hand, comprises a piston 4 which is slowly moved upwards in a cylinder 3 by a spring 7 till the partial vacuum in the cylinder is suddenly broken down and the piston moves rapidly upwards to actuate the switch or cock. The rate of movement of the piston is controlled by the entry of air into the cylinder 3 by an adjustable aperture 9 and the sudden breaking of the vacuum is caused by the piston reaching the upper end of the cylinder. In modifications, other means of breaking the vacuum, such as a hole or an enlarged cylinder bore, are adopted. A non-return valve may also be incorporated in the cylinder and the device may be oil-controlled. Reference has been directed by the Comptroller to Specifications 204,561 and 263,301, [both in Class 38 (v), Electric switches &c.].

Abstract: 1409343 Electric motors operated by thermally produced changes of permeability A PIRC 29 June 1973 [24 July 1972] 31094/73 Heading H2A In a magnetic motor having two relatively movable members and including a magnetic shunt of gadolinium or thulium metal arranged in the form of flat laminµ, and in which the laminµ are periodically heated to a temperature above the Curie point of gadolinium or thulium so as to render the laminae non-magnetic and thereby permit a magnetic flux to cause relative movement of the two members, coolant passages are disposed adjacent the laminµ so as to allow coolant fluid to come into direct contact with the laminµ and thereby reduce their temperature below the Curie point when the heating is turned off. The rotor 14 of the motor shown has six permanent magnets 40-45 and the stator 11 has two permanent magnets 24, 25. Between the limbs of the stator magnets are placed respective flux shunts each comprising gadolinium or thulium laminµ 47, Fig. 3, supported in a grid structure 48 providing coolant passages 49 through which liquid nitrogen is continually pumped. As the rotor rotates, protrusions 88-93 on the rotor close switches 74, 82 to pass current through the laminµ 47 to heat them to a temperature above the Curie point. The laminae cease to act as magnetic shunts and the stator magnets then attract the rotor magnets. When the magnets are aligned, the switches 74, 82 open and the nitrogen cools the laminµ to a temperature below the Curie point, the laminµ again act as shunts for stator magnet flux and the rotor continues to rotate under its own momentum. The stator magnets are so disposed as to provide out-of-phase torques. The complete motor has a further rotor similar to the one shown and mounted on the same shaft. The further rotor interacts with a further stator similar to the one shown. The permanent magnets may be replaced by electromagnets and the gadolinium or thulium laminµ may be heated non-electrically.
